I left on a class trip to the beach a few days ago (sweet class, right?) and during the preceding week, I busied myself on the latest gas mileage-improving methods available without cost on the internet. I ran across a few myths (like properly inflated tires don’t really save gas, nor does replacing a dirty air filter) and re-affirmed some old knowledge (cruise-control is good so long as you’re on a flat road; going 75-80 mph cuts travel time but worsens fuel economy compared with driving 55-60). I still changed my air filter (in my mind, it will help the engine start a little smoother) and properly inflated my tires (over-inflated tires have less of a tread and less resistance on the road, therefore they actually improve mileage; however, over-inflated tires also wear faster and are less safe since they provide less traction). Being the rebel that I am, I didn’t bring directions to my destination, instead relying on one of my co-pilots’s “navigator,” a GPS mapping function available on Verizon phones. For whatever reason, her navigator took us away from the interstate and onto smaller highways. This route still worked out well, because: 1)the scenery was better 2)we were not in a hurry 3)I could cruise at around 55 mph, a much more fuel-efficient speed than the 65-75 norm on an interstate.
